ayuda pliiis doy coronita

Answer 1

Respuesta:

a)3x+6=0

3x= -6

$x = \frac{ - 6}{3}$

x= -2

B) 4 (x-1) = 3x

4x-4=3x

4x= 3x+4

4x - 3x = 4

x=4

C)11x+ 6 (3-x)=3

11x + 18- 6x=3

11x-6x= 3-18

5x=-15

x=

$\frac{ - 15}{5}$

x= -3

E)

$\frac{2x - 6}{3} = x + 7$

2x-6=3x+21

2x - 3x = 21 +6

-x=27

(-1)x=27(-1)

x=-27

F)4 (y-3) + 4= -3 (y + 5)

4y -12 +4 = -3y -15

4y -8 = -3y -15

4y +3y = -15 +8

7y = 7

$x = \frac{ - 7}{7}$

x= -1
